콘크리트 펌프용 호퍼 플랩 엘보 링 {A flap elbow ring connected with a hopper for a concrete pump}Hopper flap elbow ring for concrete pumps {A flap elbow ring connected with a hopper for a concrete pump}

본 고안은 플랩 엘보와 결합되는 엘보링의 내면에 초경합금부재를 용착시켜 이송되는 콘크리트에 의해 연결부의 내면이 마모되는 것을 방지하기 위한 것이다.The present invention is to prevent wear of the inner surface of the connecting portion by the concrete transported by welding the cemented carbide member on the inner surface of the elbow ring coupled with the flap elbow.

특히 본 고안은 펌프카에서 믹싱된 콘크리트를 호퍼에서 파이프로 압출시켜 이송시킬 때 호퍼의 토출부와 이송파이프를 연결하는 플랩 엘보의 내면 이음부가 압출되는 콘크리트에 의해 마모되는 것을 방지하기 위해 초경합금부재를 설치하여 플랩 엘보의 수명을 연장할 수 있도록 한 콘크리트 펌프용 호퍼 플랩 엘보 링에 관한 것이다.In particular, the present invention installs a cemented carbide member to prevent wear of the inner joint of the flap elbow connecting the discharge part of the hopper and the conveying pipe when the concrete mixed in the pump car is extruded from the hopper to the pipe to be worn by the extruded concrete. The present invention relates to a hopper flap elbow ring for a concrete pump to extend the service life of the flap elbow.

기존에는 건설현장에서 콘크리트를 타설하기 위해 레미콘에서 펌프카의 호퍼로 콘크리트를 옮긴 후 이를 다시 펌프카에서 펌핑하여 이송파이프를 통하여 시공현장에 콘크리트를 타설하였다. 이와 같이 시공현장에 콘크리트를 타설하기 위해서는 펌프카의 호퍼에 담겨진 콘크리트를 이송 파이프로 송출하기 위해서는 호퍼 내부에 설치된 S밸브에 압력을 가하면 호퍼의 토출구를 통하여 콘크리트가 이송 파이프로 송출되도록 하고 있다. 이때 호퍼의 토출부와 이송 파이프의 사이에는 플랩 엘보가 연결되어 있으나 플랩 엘보는 토출구와 연결된 일측단 내경은 크고 이송 파이프와 연결된 타측단은 내경이 작게 형성되어 있다.Conventionally, in order to pour concrete at the construction site, the concrete was transferred from the ready-mixed concrete to the hopper of the pump car. In order to cast concrete in the construction site as described above, in order to deliver the concrete contained in the hopper of the pump car to the transfer pipe, when the pressure is applied to the S valve installed inside the hopper, the concrete is discharged to the transfer pipe through the discharge port of the hopper. At this time, the flap elbow is connected between the discharge portion of the hopper and the conveying pipe, but the inner diameter of the flap elbow is larger at one end connected to the discharge port and smaller at the other end connected to the conveying pipe.

즉, 펌프 카의 호퍼 또는 별도의 콘크리트 펌프 호퍼는 콘크리트를 고층까지 송출하기 위해 압력을 가하여 콘크리트가 이송 파이프를 통하여 원하는 지점까지 원할하게 이송되도록 하고 있다. 이때 원활한 송출을 위해서는 토출구측의 내경은 넓고 이송 파이프측의 내경은 약간 좁게 형성되어야만 일정한 압력으로 콘크리트가 이송된다.That is, the hopper of the pump car or a separate concrete pump hopper is pressurized to deliver the concrete to the high floor so that the concrete is smoothly transferred to the desired point through the transfer pipe. At this time, the inner diameter of the discharge port side is wide and the inner diameter of the conveying pipe side is formed to be slightly narrow in order to smoothly discharge the concrete at a constant pressure.

따라서 플랩 엘보의 내면은 인입측은 넓고 나가는 쪽은 좁게 형성되어 콘크리트가 이송되면서 내벽과 심한 마찰이 발생되고 더불어 마찰에 의하여 열이 발생됨으로서 플랩 엘보의 수명이 단축되어 3∼4개월 마다 교체해야하는 불편과 부품수리에 따른 비용손실이 발생되는 문제점이 있었다. Therefore, the inner surface of the flap elbow is wider in the inlet side and narrower in the outgoing side. As the concrete is transported, severe friction occurs with the inner wall, and heat is generated by the friction, which shortens the service life of the flap elbow and requires replacement every three to four months. There was a problem that the cost loss caused by repair parts.

본 고안은 이와 같은 문제점을 감안하여 고안한 것으로서, 콘크리트 플랩 엘보와 결합되는 엘보링의 내면에 초경합금부재를 용착시켜 호퍼와 이송 파이프를 연결한 플랩 엘보 내로 이송되는 콘크리트의 마찰에 의해 발생되는 마모와 열에 대한 내구성을 갖도록 하여 플랩 엘보의 수명을 최대한 연장시켜 마모에 의한 교체를 줄이는 동시에 비용을 절감할 수 있도록 함을 목적한 으로 한 것이다. The present invention was devised in view of the above problems, and the wear caused by the friction of concrete transferred into the flap elbow connecting the hopper and the transfer pipe by welding the cemented carbide member on the inner surface of the elbow coupled with the concrete flap elbow. Its purpose is to provide heat resistance to extend the service life of the flap elbows as much as possible, thereby reducing the cost of replacement.
